GLUING DEVICE FOR TI CHIGOPEE FALLS MASSACHUSETTS, A COR-- RE-W'RA'PPING MACHINES.

Application filed March 31, 195213. Serial No. 3?0,315.

T all whom it may concern.

Be it known that 1, JOHN H. Ronners, siding at Milwaukee, county of Milwaukee, State of Wisconsin, have invented certain new and useful Improvements in a Gluing Device for Tire-Wrapping Machines, of which I declare the following to be a full, clear, and exact description.

My present invention relates to a device for applying glue to the strip of paper with which automobile tire casings are wrapped helically.

It has for its object the improvement of existing machines for wrapping tire casings by the provision of means for applying glue to one edge of the strip of paper. It has for a further object a gluing device which is set-H contained and presents no outstanding parts which will interfere with the operation of the machine. It has other and further ob 'ects relating to constructional andoperating advantages which. will appear from the en: s'uing description and the appended clairns.

My invention will now be described in con- 25 nection with the accompanying drawings, in

which- I Fig. 1 is a front elevation of the machine;

Fig. 2 is a side elevation thereof;

Fig. 3 is a rear elevation thereof;

Fig. 4 is a section on an enlarged scale, taken on line 4-4. of Fig, 1 and showing the gluing mechanism in detail; 5

Fig. 5 is a section on line 5-5 of 3; and

Fi 6 is a section on line 6-4) of Fig. 4, showing the paper guide and gluing device.

A general description of the machine as a whole will first be given. The wrap ing mechanism is centered about a circular s int tle 10 having a hinged section 11 to permit of the insertion and removal ofa tire casing. The shuttle is supported for rotation by guide rollers 12 and Band is driven by contact with aroller 14 'on a shaft 15 connected by clutch 16 and gearing 17 with a motor 18.

The tire casing is supported in position to be wrapped by guide rolls 19 and 29, the lat- .ter of which is driven through shaft 21 and gearing 22 from shaft 15. Roll 19 is mounted on a shaft 23 which is driven from shaft 21. by a chain 24 and suitable sprockets. In order .to press the beads of the tire inwardly while the wrapping'is being ap lied r lls 25 and 26 aresmtably mounted, lug prefab ably pressed towards the beads by springs 27 and 28. To support thetire at its bottom and to further compress the sides of the tire rolls 29, 30 and 31 are provided, one of them,

as 31, being preferably pressed towards the tire by a spring As auxiliary devices to the wrapping mechanism about to be described a string 33 ill) may be led through a guide 34, and directed in position to be enclosed by the spiral wrapping, forming a convenient means-of cutting the wrapper from the tire; and a gummcd strip 35 may be fed from a supply 36, over a inoistening device 3?, and may be pressed against the outer circumference of the easing over the spiral wrapping by a roll 38 and a brush These mechanisms may-be used or not as desired, and form no part of my present invention.

- My invention is directed to the provision of mechanism for applying adhesive to the iii-- side of the spiral wrapping before the latter is applied to the tire. The wrapping mechanism consists in the annular shuttle 10 described above, a spool 40 of paper 41, and guides 4:2 and 43, around which the paper is led so that a suitable tension is imparted thereto, the spool and guides being mounted on the shuttle and rotating therewith. The

construction of guide i3 is preferably as fol lows: into shuttle 10, which at this point is chambered as at li to provide a receptacle for suitable adhesive, is secured a member having an opening 46 thereinconnected with chamber 44, and providing a bearing 47 for the end of a shaft 48. Guide 43 is secured to the member 4:5 as by bolts 49 passing through holes 50 in the guide and being screwed into member 45. Guide 43 has a short hole 51 registering with opening 46, and provides a bearing 52 for shaft 48. Short pins 53 disposed on the circumference of the guide serve to direct the edge of the paper. carries a small wheel 54, preferably knurled, which carries adhesive from hole 51 into contact with the inside edge of the strip of pa- Shaft 418 v .100 per; and is driven by a chain 55 from a shaft 56. lhis shaft is driven'by a chain 57 from a sprocket on spool 40 carrying the paper.

As the paper is unwound from'the spool v ed eclge 58 of the paper overlies the precediing spiral, as appears from Fig. 2, and serves to firmly unite successive turnstogether,

It will. he understood that changes in the mechanical details may he -ma ie Without de parting from the spirit of my invention as set forth in the appended claims.

I claim i; In a Wrapping machine of the type 10 wherein the paper is carried around the article in successive spirals by a rotating shuttle, a glue applying device carried by said shuttle and adapted to apply glue to the paper said device being positively actuated by the withdrawal of paper from the shuttle.

2. In a Wrapping machine of the type wherein the paper is carried around the article in successive spirals by a rotating shuttle, a paper guide mounted. on the shuttle and chambered to provide a receptacle for ailhesive, and a glue roll mounted in said guide to connect the receptacle with the surface of the guide.

3. In a Wrapping machine of the type wherein-the paper is carrieal around the article in successive spirals by a rotating shuttle a paper guide mounted on the shuttle and chambered to provide a receptacle for ad,- hesive, a glue roll mounted in said, guide to connect the chamber With the surface of the guiiie', and means for rotating the e'lue roll,

4. ln a Wrapping machine of the type wherein the paper is carried around the ole in successive spirals by a rotating shuiz'cic, a paper guide mounted on the shuttle and. chambered to provide a receptacle for adliesive, a glue roll mounted insaid. guide to connect the chamber with the surface of the guide, a paper supplying roll, and means driving the glue roll from the paper supplyingroll,

5. In a Wrapping machine of the type. wherein the paper is carried around the cle in successive spirals by a rotating she: a paper guide mounted on the shuttie chambered to provide areceptacle for hesive, and a glue roll mounted in said g to connect the receptacle with the surfaci the guide, a paper supplying roll, an inn mediate shaft, a chain connection been the paper supplying roll and the inter; ate shaft and a chain connection between glue 17012 and the intermediate shaft.

6. A Wrapping machine for annular cles comprising a rotatable shuttle, a 1 supply carried by the shuttle; a glue ap ing clevice constructed and arranpgeci to ply glue to the paper, and a glue supply cc structeii and arranged to supply glue to applying clevice, the applying device hei positively driven in a fixed relation to movement of the paper.
